Technical description

ApostropheCMS is an open-source Node.js content management system. Prior to 3.6.2, the import-export module in packages/import-export/lib/formats/gzip.js constructs an attachment source path from the attacker-controlled _id, name, and extension fields in aposAttachments.json without ensuring that the resolved path remains under the extracted attachments directory, allowing an authenticated contributor to import a crafted archive, read a host file with an allowed extension, and publish the copied file at an unauthenticated uploads URL. This issue is fixed in version 3.6.2.

——0SWE-agent's trajectory inspector (sweagent inspector), confirmed in v1.1.0, is an HTTP server that joins request paths to the trajectory directory in its /trajectory/ handler without rejecting parent-directory ('..') references, bypassing the built-in path sanitization. The server binds all interfaces (0.0.0.0), applies wildcard CORS, and requires no authentication. An unauthenticated network client (or a malicious web page via CORS) can use path traversal sequences to read files outside the intended directory. Because the read sink parses targets as trajectory JSON, disclosure is constrained to JSON files shaped like a trajectory, which can contain repository contents, command output, and secrets/API keys.1d CVE-2026-751117.5 HIG

——0Evidently UI fails to properly validate the filename parameter in the dataset materialization endpoint, allowing unauthenticated attackers to read arbitrary files outside the workspace directory. Attackers can supply traversal sequences or absolute paths in the filename field to access system files, which are then materialized into datasets and retrieved through the download endpoint.1d CVE-2026-751045.5 MED

——0Hugging Face Transformers fails to validate shard filenames in checkpoint index files, allowing attackers to read arbitrary files outside the model directory. Attackers can supply malicious index files with parent-directory references or absolute paths that are joined without validation, enabling file disclosure and filesystem reconnaissance.1d CVE-2026-543365.4 MED

——0JumpServer is an open source bastion host and an operation and maintenance security audit system. From 4.8.0 until 4.10.17, an authenticated user with SFTP permission to an authorized asset can submit crafted traversal paths through the KoKo Web Terminal SFTP feature, causing AssetDir.GetRealPath() in pkg/srvconn/sftp_asset.go to resolve paths outside the intended SFTP root and permit read, list, write, rename, or delete operations under the configured backend account on that asset. This issue is fixed in version 4.10.17.1d CVE-2026-405066.5 MED

——0OpenEMR before 8.2.0 contains a path traversal vulnerability in the standard_tables_manage.php interface where the db GET parameter is passed without validation to temp_dir_cleanup(), which joins the value to the PHP temporary directory path and recursively deletes the resulting directory. Attackers can supply a traversal sequence in the db parameter to resolve outside the intended temporary directory, and by chaining this with an open redirect in dicom_frame.php, an unauthenticated attacker can deliver a crafted URL that triggers arbitrary recursive directory deletion within an authenticated Superuser's session.1d CVE-2026-195897.1 HIG

——0Packer up to 1.15.4 is vulnerable to an issue in the third-party plugin installer that may allow unintended file system modification and could lead to code execution. A user who installs a plugin from a malicious or compromised source may be affected. This vulnerability (CVE-2026-19589) is fixed in Packer 1.16.0.1d
